Guerrilla Games has released the Horizon Forbidden West version 1.06 patch notes for your review, which includes numerous improvements for game crashes, graphics, quests, and other issues. Issues, such as graphical difficulties with swirling, sharpness, and screen vibrancy, have yet to be fixed. Guerrilla is still looking into these difficulties in the meanwhile.
Some players have noted that after associating well with Firegleam insignia, they just aren't erased from the map, and the side quest 'Breaking Even' might sometimes result in being unable to talk to Porguf when Talanah is in Camp Nowhere, preventing the quest from progressing. Both concerns are being investigated. Following playthroughs, the music track "The World on Her Shoulders" has been reported to loop indefinitely.

This patch includes a partial fix to avoid this issue from affecting players who have not yet noticed it throughout current gameplay. For those who are currently experiencing this issue, the team is still working on a solution. There have already been innumerable adjustments including both foremost and subsidiary quests issues, as well as global activities. 
If the Vibration Intensity sliders are set to 0, haptic feedback when standing next to a fireside and during fast traveling has been eliminated, and several visuals and stability issues have been fixed.
